new orks what's good?

hey guys im in new york currently and was on the internet so i thought i'd ask a few questions. for those of you who have seen the new codex im basically wondering what models you think are very good tactically. i hear stormboyz? what do you guys think the tourny army lists will mainly be made of? im curious b/c ive decided to get some orks before i get into fantasy b/c costumizing is so much fun for me and thats easy w/ orks. so when i start getting my stuff what do you guys think are pretty good to get and what is not so good? also anyone have any cool ideas for an army theme? im trying to think of a cool one to start converting my guys. any ideas? lemme know. thanks.
